WIND-MOTOR.

Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed May 27, 1920. Serial No. 384,644.

To all whom it may concern:

Be it known that I, CHARLES H. KILLOUGH, a citizen of the United States,and a resident of Wichita, in the county of Sedgwick and State ofKansas, have invented certain new and useful Improvements inWind-Motors, of which the following is a specification.

My invention relates to wind motorsformerly called windmillsand has forits general object to provide a wind-motor adapted for the driving oflight machinery of any kind by direct rotary motion. Standard windmillconstruction is unable to do this kind of driving as it only providesfor reciprocating a pitman.

The invention consists, first, in means for driving one or morecountershafts continuously; second, in means for holding the head (ormotor proper) against rotating in a horizontal plane except when thedirection of the wind is changing; third, in automatic means permittingthe head to turn during such intervals; fourth, in means forconveniently stopping the motor while the wind is blowing; and further,in certain minor features of construction and opera tion, all of whichare hereinafter set forth.

In the accompanying drawings, Figure 1 is a partial elevation of a motorembodying the improvements, many parts being shown in section; Fig. 2, asectional elevation of gearing at the base of the motor; Fig. 3, adetail of a cam and roller, viewed on line A-A of Fig. 1; Fig. 4, ahorizontal sectional detail viewed on line B-B of Fig. 1; Fig. 5, adetail view in elevation, showing certain parts seen on Fig. 1; Fig. 6,a plan view of means for controlling the vane; Fig. 7, a detail ofguides for a deflectingcable; Fig. 8, a detail viewed in section on line(3-0 of Fig. 1; Fig. 9, a plan view of the cam shown in Fig. 3.

The wind-wheel 1 and the vane are of ordinary or any preferredconstruction.

The tower 3 may be of ordinary construction excepting as hereinafternoted. The legs 3 of the tower are joined at their upper ends to a ring4 provided with a race for a ball-bearing 5, on which the head framecasting is rotatably mounted. This casting comprises the lower and upperparts 6, 7 which together form a closed housing when handhole-plate 8 ison. In the housing are split bearings 9, 10 for the wind-wheel shaft 12.

Rotation of the wind-wheel is transmitted as follows: through shaft 12,bevel pinions 13, 14, 15 to a bevel gear wheel 16, through a verticalshaft 17 which extends downward to a point near the ground-through bevelgear 18 to bevel gears 19, 20, which drive two countershafts 21, 22.

Bevel pinions 13, 14 are each keyed or p nned on shaft 12. Theintermediate. bevel pinion 15 is provided with an integral spur gear 23which drives a spur gear 24 in tegral with bevel gear 16, which is keyedon shaft 17 This gear arrangement offsets the greater wear of shaftbearings that would result from the use of but one drive pinion.

Equal wear and driving mesh of this gearing is promoted by the torsionof a spring 25 which is so clearly shown that a description of itseffect is unnecessary.

The gearing described may be run in oil. Oil may enter and fill the tube26, but cannot pass below a packing 27, having a gland 28. Shaft bearing10 also has a packed gland 29.

The bottom bearing 30 of shaft 17 is formed in a pedestal 31. The weightof said shaft is supported through the medium of its upper and lowergears 16, 18, both keyed thereon. The hub of gear 16 is mounted on anannular ball-bearing 32. The face of bottom gear 18 is formed with aball-race, turning on annular ball bearing 33 on the pedestal 31.

The vane 34, shown entire in Fig. 6, has its hub lugs 35 keyed on avertical rockshaft 36, journaled in lugs 37, 38 on the housing 67.Normally, the vane is held at an angle normal to the wind-wheel by thepull of a tension-spring 39, acting on an arm 40 fixed on shaft 36 andbeing anchored to a fixed lug 4:1.

With the wind-wheel in operation and a load on a driven shaft as 21 or22, there will be a tendency for the head to rotate bodily upon itsbearings. Such motion is of course necessary when the direction of thewind changes, but when the wind blows from one quarter, such bodilyrotation must be prevented. This is accomplished by a device illustratedon Figs. 1, 3, a and On the bottom of the lower housing part .6 is casta depending annular flange 44. In this flange is a notch 45. Justbeneath flange 44, an annular flange 4:6 is cast upon ring casting 4,and-this flange is provided with a sutlicient number of equally spacednotches 47. A latch-lever L8 is set in line with notch 45, said leverbeing pivoted on a pin 49 held by a lug 50 on casting 6. The inner endotsa'id lever lies partly in notch 45 and partly in any one of theseries of notches t'7.---On the inner arm of lever 48 is a weight 51,and on the outer end of said lever is a small roller 52. IVhen the latchformed by the inner end of the lever is held down by the weight 51, thehead or housing is heldagainst rotation. To complete the utility of thedevice, I further provide'means whereby the turning of the vane 34 onits own axis, from its normal angle, automatically releases the head andpermits it to turn. Contacting the roller 52 is a cam plate 53 havingits hub keyed upon the vane'shaft '36. In-the lower face oi the camplate is a central recess 54 formed with inclined approaches. Normally,the weight 51 holds the roller 52 up in said recess (when the vanesangle is normal). vane is deflected, either manually or by the wind,therocking of shaft 36 will turn the cam plate 'far enough to force itsroller downward a suflicient distance to lift the latch end of lever asout of a lower notch. As soon as lateral pressure upon the vane ceases,the spring 39 will restore the vane to normal angle, bringing the camrecess 54 to center, whereupon the latch end of lever 48 will drop intothe first notch it en'coun ters, thereby latching'the headto thetower asaforesaid.

In the drawing I have shown the following construction of means forstopping the wind-wheel while the wind is blowing by turning the vanethrough an angle of ninety degrees, the effect of which is well known.

.It is to be understood however that any equivalent means for deflectingthe vane may be employed, and I do not limit my claim to the followingmechanism.

Asecond crank-arm, 55, is keyedonvaneshaft 36, or it may be integralwith arm 40 as shown. The normal angles of said arms are shown on Fig.6. The operating cable 56 is connected to arm 55 as shown, passes overgrooved guide-rollers 57, 58, 59 down through the center of thehollowshaft 17 and supports a short depending rod 60 havinga nut'61 onitslower' end." Supported by this nut is a small annular ball bearingWhenever the 62, upon the upper half of which rests a crosshead 63comprising a pair of oppositely directed lugs 68' passing slid-ablythrough vertical slots 6-1: in the shaft. Mounted on lugs :68 are a pairof anti friction rollers 65, which support a nonrotary ring 66,connected pivotally by pins 67 to a yoke 68, formed intermediate theends of a lever 69, fulcrumed at about the point f to a member of thetower. Motion is communicated to this lever directly or through apull-cord 70. By drawing this down the cable'56 is drawn down when it isdesired to stop the motor, this being effected by deflecting the vane asaforesaid. The cord 70 is to be tied down until the operation of themotor is again desired. The rotation of the vertical shaft 17 will ofcourse rotate the crosshead 63, but this will not place any strain norwear upon the lever-actuated parts above mentioned.

It will thus be apparent that my invention provides a practicalwind-motor by which light machinery may be driven by continuousrotation.

By the term .head in the claims I mean to designate the rotatablehousing and the various bearings forming parts thereof.

Having now described my invention,what I claim and desire to secure byLetters Patcut is: V V
